WALL CONSTRUCTION.

Specification of Letters Patent.

Patented Jan. 6, 1920.

Original application filed March 9, 1917, Serial No. 153,697. Divided and tliis application filed May 15, 1917. Serial No. 168,701.

To all whom it may concern.-

Be it known that 1, DAVID G. BENDER, a citizen of the United States, residing at Blue Island, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Wall Constructions, of which the following is a specification.

The present invention appertains to improvements in wall constructions and in units or sections therefor, and is a division of my co-pending application Serial No. 153,697,

filed March9th, 1917, which has matured into Patent No. 1,275,121.

The primary object in View is the provision of a wall unit molded of suitable plastic material, such as concrete, the same to have its edges formed with interlocking means by which the units or blocks will be inter-connected when laid one upon another so as to resist lateral stress.

It is further comprehended within the purview of this invention to provide separate connecting members for tying together spaced rows of these molded units, the ties being of special construction so as to coact with the edge interlocking means aforesaid for the purpose of reinforcing the latter to guard against the buckling or separating of the wall along the line between the superposed rows of blocks.

Still further objects reside in the provision of the individual blocks with surface recesses into which a filler composition may be introduced to form a binder between spaced rows of the blocks, and in means for forming an air space in the wall construction.

With the above and other objects in view, this invention consists in the construction, combination and arrangement of parts all as hereinafter more fully described, claimed and illustrated in the accompanying drawings, in which:

Fig. 5 is a fragmentary perspective view of the spacing member showing more clearly its locking element,

Figs. 6 and 7 are end elevations of the spacing member used in the construction of walls with my form of block. i

Referring to the drawings. I have illustrated in Fig. at the preferred form of block or unit which is used in a wall construction such ashereinbefore proposed. will be observed, this block is preferably very narrow so as to substantially constitute a veneer and it is molded of a suitable composition or concrete, such as is well known in the art to which this invention relates. It is molded preferably by apparatus set forth groove formations. As indicated in Fig. 3

of the drawings, this thin block may be attached to the side of a building, designated 4, to furnish an exterior finish therefor, headed spikes or nails 5 being driven into the building wall and the headed extremity bent into the groove of the adjacent block.

In the use of the block for a foundation or other wall they are preferably laid in spaced rows and a plastic filler, such as indicated by the reference character 6 introduced therebetween, so as to form a relatively thick and solid wall. Each of the blocks is preferably provided at least on one of its surfaces with a plurality of recesses 7. and the filling material will become lodged in the said recesses during the filling operation. hen the filler dries or hardens, there will be a positive interlocking of the filler with the walls which tends to hold the blocks against displacement.

I do not depend upon this interlocking action alone, however, inasmuch as I provide tie members 8, as shown most clearly in Fig. 2, for connecting the respective blocks of the spaced walls together. These tie members form a very essential feature of my wall construction. Each of the same is bent angularly at its end to form an arm 9 which is introduced into a suitable recess 10, formed in molding the blocks, the extremity of the tie rod being bent back upon itself and twisted as indicated at 11, so as to form a loop. It will be observed that the. extreme end of the tie in conjunction with the main portion of the rod forms a V- v shaped seat, as indicated at 12, into which the tongue 2 of a superposed block seats in the formation of the particular wall. The object of this arrangement is to tie the spaced walls together and at the same time provide a reinforcing, interlocking connection between the superposed rows of the blocks in the respective walls, whereby the wall will be very strong to resist lateral pressure along the lines separating the rows of blocks. Each block, it may be stated, is formed with a suitable number of the recesses 10, so that it is not necessary that the recesses in the blocks of the separating rows be directly opposite each other in building up the wall. A coating of liquid cement is given the edges of said blocks, and the recesses are also filled with this cementitious paint after the ties have been introduced in place. r Where it is desired to provide an air space between a two wall construction of thistype, I employ spacing means such as is shown in Figs. 5, 6, and 7. This spacing means consists of the spacing member 13, to one side of which are suitably connected vertically arranged cam members 1%, there being one of such members at each end of said member. Each cam member is prorided with an angular terminal 15 at its top constituting manipulating means for rotating the cam, and said cam members are connected to the spacing member by means of suitable hinges 16. At the opposite side of the cam member is hingedly connected a flexible locking plate 17, held against the side of the member 13 by guides or keepers 18, These locking plates are serrated at one edge as indicated at 19, so that when the cam members are operated they will engage with the tie members in position to sustain the filling material which poured between said spacing members and one of the walls. After the filling material has become set, the spacing member may readily be removed by operating the cam members and the processof building up the wall continued in the same manner.

In addition to the recesses 10, inthe molding of the blocks or units, I preferably provide transverse grooves 10' to receive the tie member, as will be clearly understood by reference to Figs. 1 and 2 of the drawings. I do not wish to be confined to the formation of the recesses 7 in only one face of the block as it is clearly feasible to provide such recesses in both faces of the block where such may be desired.

Having thus described my invention. what I claim as new is:

V 1. As a new article of manufacture, a tie member for connecting two rows of wall units and the units of each wall, consisting of a single length of wirebent at substantially a right angle at each end, the end portion being then twisted back on the bent portion and away from the latter at the extremity to forma seat for the wallunit,

2. In a wall construction, spaced walls each consisting of individual units laid one upon another, and tie members connecting the said rows, each member being bent angularly in a downward direction adjacent to its end to provide engaging means for a relatively lower unit of one wall, the extremity of the tie being twisted back on the downward bent portion and laterally to provide engaging means for an upper unit of said wall.

3. In a wall construction, spaced rows of blocks, the blocks of each row having tongue and groove connections, each block having tie receiving recesses, and tie members disposed in said recesses, each member having its end bent angularly and twisted to form connecting means comprising an arm for a relatively lower block and a V- shaped seat for a block superposed relative thereto for connecting the blocks of the respective rows together,

4:. In a wall construction, spaced rows of blocks, each block having. a vertical recess, a tie member for connecting the rows together having its end twisted to form a loop constituting an arm provided with a tongue receiving seat at its uppermost end, the blocks of the walls having tongue and groove connections, the tongue of one block co -acting with the tongue receiving seat of the tie member arm, said arm extending intov the lower block.

In testimony whereof I aflix my signature.
